Description

Technical Field

[0001] This invention belongs to the field of video surveillance equipment technology, specifically a monitoring device and method for studying vegetation degradation in mines. Background Technology

[0002] As my country's mining development moves towards large-scale and intensive operations, the disturbance to the ecological environment caused by open-pit mining and spoil disposal activities is becoming increasingly prominent. Against this backdrop, soil erosion and vegetation degradation have become core issues in the field of mine ecological environment protection. Video monitoring of vegetation using monitoring equipment can provide data support for research on vegetation degradation patterns and the effectiveness of prevention and control measures.

[0003] In conducting video surveillance of vegetation in mines, existing conventional monitoring equipment mostly employs aerial photography, capturing images of vegetation from above within the monitored area. In practice, this type of equipment is limited by factors such as installation location and vegetation obstruction, only able to capture images of surface vegetation. The imaging effect on lower-lying herbs, shrubs, and other small plants is poor, especially in areas close to the ground. Due to the complex environment of mining areas, conventional mobile monitoring equipment struggles to navigate through vegetation, often requiring manual labor for related filming and monitoring work, resulting in significant filming difficulties and high labor costs.

[0004] In order to improve the mobility of monitoring equipment, a rail-mounted agricultural monitoring equipment installation mechanism has been disclosed in related technologies. In this solution, by setting up a rail and other structures, the monitoring equipment can move along the rail and thus change the shooting position. However, when applied to mining areas, on the one hand, the cost of setting up the rail is high and difficult, making it inconvenient to cover the mining area. On the other hand, since the position of the rail is fixed, it can only shoot the area along the way, which is not conducive to the comprehensiveness of the shooting data.

[0005] In view of this, the present invention proposes a monitoring device and method for studying vegetation degradation in mines, in order to solve the above-mentioned technical problems. Summary of the Invention

[0030] The beneficial effects of this invention are as follows:

[0031] 1. The monitoring equipment and method for studying vegetation degradation in mines as described in this invention, by setting up a vertical deployment mechanism, utilizes a rotating ring mounted on an installation column, in conjunction with a retractable extension cable, to achieve the effect of switching and changing the position of the monitoring subject within the monitoring range. During the change of the monitoring subject's position, the monitoring subject moves into the interior of the vegetation and takes pictures of the vegetation composition from top to bottom.

At the same time, during the process of tightening the extension cable to reset, it can also reduce the probability that the monitoring body will be blocked and unable to reset.

[0043] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0044] like Figures 1 to 8 As shown, the monitoring equipment for studying vegetation degradation in mines according to the present invention includes a mounting column 1 and a monitoring body 11 installed on the mounting column 1;

[0045] It also includes a vertical projection mechanism, which is used to connect the monitoring body 11 and the mounting column 1, and the vertical projection mechanism is used to expand the monitoring range of the monitoring body 11;

[0046] The vertical delivery mechanism includes an extension rail 2, a rotating ring 21, a rotary motor 22, an extension cable 24, a take-up roller 25, a drive motor 27, and a mounting base 26.

[0047] The rotating ring 21 is rotatably mounted on the mounting column 1, and an extension rail 2 is mounted on the rotating ring 21, which extends in the horizontal direction;

[0048] The rotary motor 22 is fixedly mounted on the rotating ring 21, and a drive roller 23 is fixedly mounted on the output end of the rotary motor 22. The drive roller 23 is driven by friction with the mounting column 1.

[0049] An extension cable 24 is installed on the extension rail 2. The end of the extension cable 24 away from the extension rail 2 is wound and installed on the take-up roller 25. The take-up roller 25 is rotatably installed on the mounting base 26.

[0050] The drive motor 27 is fixedly installed inside the mounting base 26. The output end of the drive motor 27 is fixedly connected to the take-up roller 25. The monitoring body 11 is installed on the mounting base 26.

[0051] When studying and addressing vegetation degradation in mines, it is necessary to monitor the vegetation in a timely manner and understand the actual effects of degradation intervention measures. In order to obtain more detailed data, it is necessary to periodically photograph the leaves, branches, and rootstocks of the plants to provide data support for degradation intervention research. In this process, the setting of a vertical projection mechanism, together with the monitoring body 11, can more conveniently obtain vegetation information.

[0052] Specifically, in practical applications, for vegetation monitoring, most of the time it is only necessary to obtain information on the vegetation coverage area and surface condition. However, when more detailed plant conditions are required, it is necessary to sample and photograph the plants within the monitoring range. Ideally, the photographs should cover the parts of the plants above the ground. Therefore, this invention includes a vertical projection mechanism. In normal use, the monitoring body 11 is suspended in mid-air with the cooperation of the mounting column 1 and the vertical projection mechanism, enabling large-scale monitoring of the vegetation and real-time detection of significant changes over a wide area. In further detailed studies, a preset program is remotely controlled to start the rotary motor 22, which in turn causes the drive roller 23 to rub against the mounting column 1. Under the action of friction, the rotating ring 21 rotates around the mounting column 1, while the extension rail 2 and other structures mounted on the rotating ring 21 rotate synchronously. The images captured by the monitoring body 11 located at the end of the extension rail 2 are then captured. This allows staff to select suitable shooting positions. Once the shooting position is determined, the drive motor 27 starts under the control of a pre-set program. The drive motor 27 drives the take-up roller 25 to rotate, causing the extension cable 24 initially wound on the take-up roller 25 to gradually loosen. Under the action of gravity, the mounting base 26 and the monitoring body 11 on it gradually descend. As the monitoring body 11 descends from the gaps in the vegetation to the ground, it takes pictures of the canopies, branches, and root systems of trees, shrubs, and grasses along the way. When the monitoring body 11 reaches the ground, the program controls the drive motor 27 to rotate in the opposite direction, cooperating with the take-up roller 25 to rewind the extension cable 24, which allows the monitoring body 11 to rise and reset. By repeating the above operation, the monitoring body 11 can be raised and lowered multiple times at different locations in the mine vegetation. The images taken during these multiple raising and lowering processes provide data support for the study of mine vegetation degradation.

[0053] This invention, by setting up a vertical delivery mechanism, utilizes a rotating ring 21 mounted on the mounting column 1, along with a retractable extension cable 24, to achieve the effect of switching and changing the position of the monitoring subject 11 within the monitoring range. During the change of the position of the monitoring subject 11, the monitoring subject 11 moves into the interior of the vegetation and takes pictures of the vegetation composition from top to bottom. This not only effectively improves the detail of the vegetation pictures and provides more accurate data support for vegetation degradation, but also enhances the adjustability and controllability of the shooting position.

[0054] In a preferred embodiment of the present invention, the extension rail 2 is hingedly mounted on the rotating ring 21, and a control ring 3 is rotatably mounted on the mounting column 1. The control ring 3 and the rotating ring 21 are fixedly connected by a connecting rod 31. An electric control rod 32 is hingedly mounted on the control ring 3, and the end of the electric control rod 32 away from the control ring 3 is hingedly connected to the extension rail 2.

[0055] The mounting post 1 is provided with a threaded guide groove 33, and the rotating ring 21 is engaged with the threaded guide groove 33.

[0056] In this invention, before the vertical deployment of the monitoring subject 11, the starting of the rotary motor 22 not only causes the rotating ring 21 to rotate, but also utilizes the engagement of the rotating ring 21 with the threaded guide groove 33 to cause a change in the vertical height of the rotating ring 21 during rotation, thereby changing the starting height of the extension rail 2. When adjusting the deployment position of the monitoring subject 11, the extension and retraction of the electric control rod 32 causes a change in the angle of the extension rail 2. Combined with the change in the orientation of the extension rail 2 caused by rotation, the landing point of the monitoring subject 11 can be adjusted more flexibly within a controllable range. At the same time, the presence of the electric control rod 32, together with the mounting column 1 and the extension rail 2, forms a triangular structure to enhance the stability of the vertical deployment mechanism.

[0057] In a preferred embodiment of the present invention, the drive motor 27 is a dual-head motor, and a walking wheel 28 is rotatably mounted on the mounting base 26. The walking wheel 28 is connected to the output end of the drive motor 27 through a transmission wheel set.

[0058] To further expand the shooting range and enhance shooting flexibility, in this invention, when the drive motor 27 rotates, it also transmits power to the walking wheel 28 through the transmission wheel set, causing the walking wheel 28 to rotate. During the descent of the mounting base 26, the rotation of the walking wheel 28 reduces the probability of the mounting base 26 staying on the tree trunk. It should also be noted that when the mounting base 26 descends to the ground, the side with the walking wheel 28 is heavier, causing this side of the mounting base 26 to adhere to the ground. As the drive motor 27 continues to rotate, the friction between the walking wheel 28 and the ground will cause the mounting base 26 to move. In other embodiments of this invention, the mounting base 26 is also equipped with a forward direction control mechanism, which, together with the walking wheel 28, further enhances the controllability of the movement of the mounting base 26 on the ground.

[0059] As a preferred embodiment of the present invention, it also includes an obstacle avoidance and clearing mechanism, which is installed on the mounting base 26. The obstacle avoidance and clearing mechanism is used to clear the descent path of the monitoring body 11. The obstacle avoidance and clearing mechanism includes a telescopic shell, a push rod 45, a connecting ring 44 and a cam 43.

[0060] The telescopic outer shell is fitted onto the mounting base 26, and the telescopic outer shell is a spindle-shaped hollow structure with openings at both ends;

[0061] The mounting base 26 has a transmission cavity 42 inside. A cam 43 is rotatably mounted on one end of the transmission cavity 42 near the drive motor 27. The cam 43 is connected to the output end of the drive motor 27.

[0062] A connecting ring 44 is slidably installed in the transmission cavity 42. The connecting ring 44 is located on the rotation path of the cam 43. A push rod 45 is hinged to the connecting ring 44 in the circumferential direction.

[0063] The mounting base 26 is provided with a deflection groove 46, and the push rod 45 extends to the outside of the mounting base 26 through the deflection groove 46. The push rod 45 is located at one end outside the mounting base 26 and is hinged to the telescopic shell.

[0064] The telescopic outer shell is composed of an elastic membrane 4 and an arc-shaped piece 41. The arc-shaped piece 41 is fixedly installed at equal intervals on the inner side of the elastic membrane 4, and the arc-shaped piece 41 is connected to the push rod 45.

[0065] Since the mounting base 26 often needs to pass through gaps in branches and leaves during downward deployment, to reduce the probability of interception, in this invention, when the drive motor 27 rotates, the drive motor 27 drives the cam 43 to rotate. The connecting ring 44 located on the rotation path of the cam 43 is pushed. Under the transmission action of the push rod 45 hinged on the connecting ring 44, the telescopic shell expands outward. As the cam 43 continues to rotate, when the connecting ring 44 loses the push from the cam 43, the telescopic shell returns to its original position under its own elasticity. Combined with the transmission action of the push rod 45, the connecting ring... 44 Reset, in conjunction with the continuous rotation of cam 43, causes the telescopic shell to expand and contract regularly. Since the telescopic shell has a spindle-shaped structure, it can better avoid the obstruction of branches. With the regular expansion and contraction of the telescopic shell, it can effectively enhance the efficiency of the mounting base 26 in passing through tree trunks and branches. Combined with the active avoidance of overly dense branch environments when the staff selects the lower position in the early stage, it reduces the probability that the mounting base 26 and the monitoring body 11 on it cannot reach the ground. At the same time, during the process of tightening the extension cable 24 to reset, it can also reduce the probability that the monitoring body 11 will be blocked and unable to reset.

[0066] In a preferred embodiment of the present invention, adjustment grooves 5 are provided on both sides of the transmission cavity 42, and a gravity block 51 is slidably installed in the adjustment groove 5. The gravity block 51 is rotatably connected to the cam 43, and the cam 43 is connected to the output end of the drive motor 27 via a belt drive 52.

[0067] The total weight of the gravity block 51 is greater than the deformation force of the elastic membrane 4, and a reset spring 53 is fixedly installed at the end of the adjustment groove 5 facing the extension cable 24.

[0068] When the mounting base 26 is in mid-air, the adjusting groove 5 is vertical. Under the action of gravity, the gravity block 51 moves downward, causing the cam 43 to approach the connecting ring 44. At this time, the elastic band 52 is taut. When the drive motor 27 starts, the elastic band 52 drives the cam 43 to rotate, which in turn pushes the connecting ring 44, causing the telescopic housing to expand and contract. Since the center of gravity of the cam 43 is close to the initial position of the connecting ring 44, the expansion and contraction range of the telescopic housing is increased. When the mounting base 26 reaches the ground, under the support of the ground and the action of the center of gravity of the mounting base 26, the side of the mounting base 26 with the traveling wheel 28 is attached to the ground. With the groove parallel to the ground, the elastic band 52 is in a state of reduced tension. Due to the stretchable nature of the elastic band 52, the rotation of the drive motor 27 can still drive the cam 43 to rotate. When the cam 43 rotates, it pushes the connecting ring 44 and the push rod 45, causing the telescopic shell to expand and contract. However, since the telescopic shell is close to the ground at this time, under the gravity of the mounting base 26 and other structures, the telescopic shell can only expand and contract slightly. Under the action of the reaction force, the rotation of the cam 43 causes the cam 43 itself to move away from the connecting ring 44. That is to say, the gravity block 51 moves towards the return spring 53. Therefore, when moving on the ground, the resistance of the expansion and contraction of the telescopic shell to the movement can be effectively reduced.

[0069] In a preferred embodiment of the present invention, the extension cable 24 includes multiple steel wire ropes, and the arc-shaped plate 41 has a transfer hole 47. The steel wire ropes correspond one-to-one with the transfer holes 47, and the steel wire ropes extend to the take-up roller 25 after passing through the transfer holes 47.

[0070] To further reduce the probability of the mounting base 26 getting stuck during retrieval, the extension cable 24 in this invention is composed of multiple steel wire ropes, each with a central transfer hole 47. When the drive motor 27 rotates, the telescopic outer shell expands and contracts, meaning that the spacing between the multiple arc-shaped pieces 41 increases and decreases regularly. During this process, the spacing between the multiple steel wire ropes also decreases, thereby using the steel wire ropes to push the branches, so that the mounting base 26, which is fitted with the telescopic outer shell, can pass through the gaps in the branches and be retrieved.

[0071] A monitoring method for studying vegetation degradation in mines, comprising the following steps:

[0072] A1: Divide the monitoring points according to the area of ​​the mine vegetation to be studied, and install monitoring equipment at the monitoring points. The monitoring equipment will conduct all-weather comprehensive detection of the mine vegetation from high altitude and record the vegetation coverage area in real time.

[0073] A2: Under remote manual control, the vertical delivery mechanism and the obstacle avoidance and clearing mechanism work together to periodically lower the monitoring body 11, causing the monitoring body 11 to extend downward and take pictures of the plants along the way from top to bottom.
